Application filed September 20, 1916. Serial No. 121,108.

To all whom it may concern: 7

Be it known that I, J 0111* J. M GUIRL, citizen of the United States, residing at Midland, in the county of Beaver and'State of Pennsylvania, have invented certain new and useful Improvements in Self-Lubricating Devices, of which thefollowing is a specification.

This invention relates to self lubricating devices, and has for its object to provide a device of such class, in a manner as hereinafter set forth, for automatically lubricating a shaft or journal during the operation of the latterl 7 Further objects of the invention are to provide a self lubricating device which is comparatively simple in its construction and arrangement, strong, durable, efficient in its use, readily set up, automatic in its action, and inexpensive.

With the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment.

of the invention, but it is to be understood. that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views Figure 1 is a side elevation of a self lubricating device in accordance with this in.- vention showing the-adaptation thereof in connection with an axle shaft and its bearing.

Fig. 2 is a top plan view of the device.

Fig. 8 is a section on line 3--3, Fig. 2 looking in the direction of the arrow.

Fig. 4 is a section on line t--4,Fig. 2, looking in the direction of the arrow.

Referring to the drawings in detail l denotes a portable body having a support 5 de pending therefrom and the said support 5 is flanged as at 7, 8. Extending through the flanges 7, 8, are securing devices 9, 9 for connecting the support 5 to the body 1.

The support 5, has its lower portion, centrally thereof, cut away to provide a chamber 10, the bottom of which is formed by a plate 12, connected against the support 5 by securing devices 11. r

. The reference character 2 denotes an axle rail. isindicated at 13 and upon which use els a wheel 3 carried by the axle 2. The hub of the wheel is indicated at 1-.

Mounted upon the plate 12, within the chamber 10, is a receptacle 14:, which provides a well. 15 for lubricant. The receptacle 14: has flanges 16, through which extend securing devices 17, for fixedly securing the receptacle 1 upon the plate 12.

Positioned within the well 15., is a U- shaped member 17. The vertical arms, of the member 17, are indicated at 18,19, and each of said. arms, near its upper end, is formed with a pair of slots 20. Theslots of each pair of slots are spaced from each other. Positioned against the face of each of the vertical arms of the member 1 1, near the top thereof, is a shiftlng plate21, and

the said plates 21 bear against shaftsj22, of

a pairoffced rolls 23. Each of the. rolls such an arrangement the feed rolls 23 can be shifted vertically. Surrounding each roll 23 and extending between the head pieces 24; is a covering 25 which may be of leather, cloth, rubber, or other suitable material. By

7 the arrangement set forth when the cover ing 25 becomes worn it can be removed and a new one substituted. The covering 25 can be roughened or knurled.

Each of the shifting plates 21, centrally of its lower edge is formed with an in} wardly extending tongue 26 over-lapped by an end of a follower 27 and the latter at each of its ends is slitted to form a series of ears 28, 29 and 30. The tongue 26 of a plate 21, extends'upon t'heear 30 and is over-lapped bythe ears 28, 2.9 and by such an arrangement the follower 27 is coupled to the plates 21 so that when the follower 27is moved upward the plates 21 will be carried therewith and shift the feed rolls 23.

Fixedlv secured to the follower 27, centrally of its lower face, by the fastening devices 31, is a pair of arcuate resilient members 32, which are connected together centrally by a clip 33, the latter having the fastening devices 31 extending therethrough. lnterposed between the clip 33 and the bo t tom of the member 17 is an expansion spring 34: which has its. upper coil positioned between the members 82and the follower 27 as at 35. The members 32 limit compression of the springs 34, as wellas act in conjunction with the springs 34, to elevate the follower.

The function of the spring 34: is to force the feed rolls 28 upward and to maintain them in engagement with the shaft 2. Thesaid rolls 23 travel within the lubrii bent in the well and asthe shaft 2 revolves', the rolls 23 will also be revolved to automatically feed the lubricant to the shaft 2. V The operation of the said rolls 23 is due to the friction between the said rolls and the shafts and bysuch an arrangement it is obvlous that the lubricating device is what may be termed a friction operative device 7 for the purpose of feeding lubricant to a shaft or journal.

What I claim is 1. A self lubricating device comprising a pair of feed rolls adapted to engage and be operated by the element to be lubricated,

pair of feed rolls adapted to engage and be operated by the element to be lubricated, a

lubricant reservoir, a U-shaped member adapted to be arranged therein and having the shafts of the rolls extending therein, elevating plates engaging with said shafts for moving said rolls toward the element to'be lubricated, a follower connected with said plates for. vertically moving them, means connected with the follower and abutting against said member for shifting the 'latter,- and: a removable cover for each of said rolls. V

3. Aself lubricating device comprising a pair of feed rolls adapted to travel in a body of lubricant and engaging and operated by Copies of. this patent may be obtained for the element to be lubricated, a lubricant reservoir, plates abutting against the shafts of said rolls for shifting these latter to engage said element for supplying lubricant thereto,a follower connected with said plates for vertically moving the same, and means for shifting the follower.

4. A self lubricating device comprising a pair of feed rolls adapted to travel in a body of lubricant and engaging and operated by .the element to belubricated a lubricant reservoir, plates abutting against the shafts of said rolls for shifting these latter to engage said element for supplying lubricant thereto, a follower connected with said plates vertically moving the same, resilient members arcuate in contour connected to and depending from the follower, and a coiled spring having its upper end extending be tween the follower and said resilient members, and a removable covering for each of said rolls.

6. A lubricating device comprising a lubricant feeding means adapted to travel in a body of lubricant, a lubricant reservoir, elevating plates for said feeding means, a follower connected to said elevating plates for shifting the same, resilient elements connected to and depending from said follower, and a coiled spring having its upper coil interposed between said resilient members and said follower.

In testimony whereof I aiiix my signature in the presence of two witnesses.

JOHN J. MCGUIRL.
